Isovist topology analysis in scenic spot planning

Isovist analysis is the important analysis method in the scenic spot planning. The traditional isovist analysis is based on the line of sight and the viewshed of sight in GIS, which is ground on the single point of sight. The main problem of this kind of isovist analysis is short of the relation with the structural composition of the scenic spot, such as the trail organization and the architecture location selection. The topology analysis is the main tool of the social networks analysis. In the paper, we select Q analysis, which is one method of the topology analysis, as the analysis tool to combine the isovist analysis of GIS with the social networks analysis, and put forward to the concept of sight structure of isovist quantification analysis method on the example of Baizhangji-feiyun lake scenic spot, Wenzhou, Zhejiang province. In brief, we could integrate the single isovist view or isovist with Q analysis so that we could relate the single isovist with the whole landscape structure, which could help us confirm the suitable location of landscape architecture.
